Omnicom Media Group announced a mobile-focused deal with Twitter on Tuesday, worth $230 million over the next two years.

The deal will integrate Omnicom’s programmatic ad buying unit Accuen with Twitter’s ad exchange MoPub, which it purchased for a reported $350 million in September. In addition to locking in ad rates and inventory access for Omnicom agencies, the arrangement will also give the holding company a “first look” at new ad units and opportunities being developed by the social network. Like many of these deals, it will include an element of “research,” the companies said.

“This is the first holding company agreement we’ve done on the mobile ad exchange side,” said Twitter’s president of global revenue, Adam Bain, adding, “It’s great for us because we’ll now have high-quality advertisers coming through the exchange.”

Twitter has struck similar partnerships with other holding companies over the past two years. Last April it signed one with Publicis-owned Starcom MediaVest Group worth a reported $200 million over two years, for example.
